**What type of hardware are you using** : Other(?)
**What YunoHost version are you running** : 11.3.0
**What app is this about** : Pleroma
### Describe your issue
When I try to use the pleroma instance frontend, I get:
{“errors”:{“detail”:“Internal server error”}}
Other clients work, so it seems to be a front-end only issue.
And yes: I DID mess with the frontend. I must have botched the installation of Mangane. But now I can’t access the frontend, nor the old admin-panel, all return “Internal server error”. Deleting the Mangane directory did not fix it.
Unfortunately, I couldn’t find any useful log other than that 500 code.

Have you tried to turn back to default frontend?
If it’s the case, have you still the error?

Look at this doc, it can help… But in French.
> **[Installer Mangane pour Pleroma sur Yunohost - HedgeDoc](https://pad.tmprs.net/yuPUXErjS0SOQaSYJM9YgQ#)**
In short :
```auto
sudo su pleroma -s $SHELL -lc "/var/www/pleroma/live/bin/pleroma_ctl frontend install mangane --ref dist --build-url https://github.com/BDX-town/Mangane/releases/latest/download/static.zip"
```
Done

That’s my issue: how do I get back to the default front-end?
The doc uses the admin FE to do so, but I can’t access that either.

You can also remove Mangane manualy from the CLI.
Command:
```auto
sudo rm -fr /home/yunohost.app/pleroma/static/frontends/mangane/
```
This does’nt modify Pleroma, just remove the Mangane files…

I tried both of the above (already tried restarting the service with systemctl before), still no luck.

Have you tried to visit your instance in `private mode` and/or do a `ctrl-cap-R` (to empty the cache of your browser?

Sooo! Not sure what did it but after a system upgrade (regular, not Yuno 12), I actually tried to access the old admin panel from a different browser (Chromium, usually I’m on FF), and it worked!
There, I saw that somewhat the default Pleroma-FE was proposed for… installation!!
I clicked “install”, and that fixed it!
What I think happened: after botching the Mangane installation, I must have accidentally deleted the default front-end, thus no way to recover it except from the admin panel. Access to the admin FE was not working but probably because of a cache issue.
I didn’t suspect the 2 would fail for a different reason, so I may have skipped some basic checks! But all in all, it was a cache issue, just not where I thought.
So thank you!
